[Bug]: SMB webdav Exception "Malformed state response from server", "Undefined index: attributes"

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

Files can not be synchronized from an Android device with "Nextcloud Android App" into the SMB storage location.
Or alternatively files can not be moved within the SMB storage via the browser GUI.
Instead the following errors are reported

webdav: Icewind\SMB\Exception\Exception: Malformed state response from server
PHP: Error: Undefined index: attributes at /var/www/nextcloud/apps/files_external/3rdparty/icewind/smb/src/Wrapped/Parser.php#155

Steps to reproduce

1. Install nextcloud version 24.0.1 on a Debian 11 Bullseye server
2. Install the smbclient 4.13.13 to attach SMB-shares as external storage
3. Attach external storage backend by a SMB-share on same Debian 11 Bullseye Server
4. Install Nextcloud Android App 3.20.3. on mobile device
5. Configure folder for automated sync in the mobile App
6. Put files in the configured folder on the mobile device

Instead of step 4. to 6. also a file within the SMB share could be moved in the browser GUI.

Expected behavior

The file is uploaded to Nextcloud storage.

Additional info

Problem arose after upgrade of nextcloud sever (major versions). Worked well before.

There is an similar bug nextcloud/server#30751 created recently also effecting the external SMB but with different error message. Bug nextcloud/server#30751 reports "Unknown error (NT_STATUS_OBJECT_NAME_INVALID)", this bug reports "Undefined index: attributes".

The problem is also mentioned in the nextcloud.com forum: https://help.nextcloud.com/t/smb-share-not-available/134928

Start with apps/files_external/3rdparty/icewind/smb/src/Wrapped/Parser.php at line 155 and follow the stat path through Share.php line 217 and apps/files_external/lib/Lib/Storage/SMB.php lines 193 and 668. Reproduce an upload or browser MOVE against the SMB external storage and inspect the returned state. Done means these operations complete without the undefined-index or malformed-state errors.
